VEHICLES-WHEEL.

Specification of Letters Patent.

Application filed July 10,1905. Serial N0- 268,973-

Patented Sept.- 4, 1906.

T0 all'whom it may concern:

Be it known that I, ANDERS H. KOPPERUD, acitizen of the United States, residing at Byron, county of Contra Costa, State of Cali fornia, have invented certain new and useful Improvements in Vehicle-Wheels; and I hereby declare the following to be a full, clear, and exact description of the same.

The present invention is mainly designed to serve as a substitute for the ex ensiverubher-tired wheels at resent use in connection with automobi es, the object being to provide an inexpensive, durable, and efficient metallic spring-wheel for automobiles.

The hereinafter-described wheel consists of a suitable hub, from which spring a series of curved metallic spokes, the outer end portion of each spoke being. rearwardly curved and, together with such portion of the remainin spokes, forming the tread of the wheel, sai

tread consisting of a series of independent treadsections.

To com rehend the invention, reference should be ad to the accompanying sheet of drawings, wherein- Fig. 2 is a front view of the .wheel. Fig. 3 is a detail view of one of the metallic spokes. Fi 4 is a detail view of the hub of the wheel with the spokes removed therefrom. F ig. 5 is a vertical sectional view of the hub, illustrating the spokes secured therein; and Fig. 6 is a lon itudinal sectional view of the hub, the spokes being secured therein.

1 The numeral 1 designates the hub of the wheel, and 2 3 the cheek or side plates thereof. Between these pl ends of the cokes 4 are secured, said spokes being secure to the cheek-plate 2 by means T of the pins or studs 5. These studs or pins extend within the eye 6 of the spokes and through the said cheek-plate 2, being secured in position by means of the nut 7, which screws onto the screw-threaded rojecting end of the said pins or studs. he united ends of the-spokes 4 are covered and held in place by means ofthe cheek-plate 3, which plate slips onto the hub 1 and is united to the' plate 2 through the medium of the securingolts 8. These bolts extend through the said cheek-plates, passing between the inner end portions of the spokes, and are drawn tight by means of the n ts 8'. formed with t e projecting tongues .9 9' which when the plates are brought together ates the inner The cheek-plates are interlock one with the other and form a bearing for the inner end portion of the spokes, which pass between the said tongues.

The s okes 4 are formed of spring metal and pro erably the. center or bodyportion of each spoke is curved forwardly, so as to give requisite resiliency thereto. The outer end portion of each spoke is rearwardly curved on the arc of a circle, thereby providing a curved tread-section 10 to each spoke,.wh1ch tread-sections when the spokes are properly positioned form an outer metallic tread for the wheel. The inner face of each tread-section is channeled or grooved on its inner face,

the outer face thereof being slightly rounding. The spokes are so shaped and located relative to each other that approximately one-half of each tread-section l0 rests within the grooved or channeled portion of the treadsection of the preceding spoke, while its outer portion overlaps the inner portion of the tread-section of the subsequent spoke, the tread-sections thus interlocking one with-the other, and forming a continuous outer tread for the wheel. p

To aid or assist in the climbing or mils, the outer ex osed portion of'each tread-sectionis formed with one or more projecting ribs 12.

It will be understood that-the end of each tread-section terminates in a feather-edge, thereby giving substantially an even surface to the wheels tread.

It will be understood that the she e 'o'flthe spokes may be changed or modifie as des red.

. In case of a spoke breaking or becoming damaged the same may be readily replaced. To this end it is only required to separate the cheek-plates 2 3, remove the pin or stud 5 se curing such damaged spoke, detach the said spoke, and insert a new one in place thereof, t e parts then being replaced to secure the spoke in proper osition.

The feature .0 the invention is the forming of a resilient wheel from a series of spokes, each spoke comprising an independent treadsection, which tread-sections interlock one with the other, so as to form a continuous outer tread.

While I have described-my invention as particularly adapted to vehicle-wheels, it is obvious that it may also be adapted to pulley or other wheels when it is desirable to have a. resilient tread-surface.

Having thusdescribed the inventiomwhat ICO IOF,

is claimed as new, and desired to be protected byLetters Patent, is

1. A resilient Wheel having the spokes thereof extended to form a yieldable treadsurface and provided with traction-lugs.

2. A resilient Wheel comprising a hub and yieldable s okes secured to the hub and having their ee ends overlapping to form a tread-surface and provided with traction devices.

3. A resilient vehicle-Wheel comprising a hub, and a series of spring-spokes, extending radially therefrom and having their outer ends bent rearwardly to form tread-sections, the outer surfaces of said tread-sections being provided with projecting portions.

4. A spring-wheel comprising a hub, a series of radially-disposed spring-spokes secured thereto at their inner ends and having their outer ends bent. rearwardly to form tread-sections, the tread-sectionsof ad acent spokes overlapping -to form a continuous tread-surface and having their outer surfaces provided with projecting portions.

5. A spring-Wheel comprising a hub, a series of radially-disposed spring-spokes connected theret 0 at their inner ends and havi their outer ends bent rearwardly on the arc of a circle to form tread-sections,' eoncavo-conv vex. in cross-section, the tread-sections of. each spoke being arranged to overlap and interlock with the tread-sections of the adjacent spoke for an appreciable portion of the length thereof.

6. A resilient vehicle-wheel, the same consubstantially radially therefrom, th body portions of said spokes being curved forivardly and the end of said spokes being curved rearwardly on the arc of a circle to form tread-sections directly overlying the connection of their respective spo es with the huh, the treads ections of adjacent s okes being arranged to overlap and provide with portions adapted. to interlock to prevent lat.- eral movement thereof,

In testimony whereof I have-hereunto affixed my signature in the presence of two witnesses.
